Notes:
1.
Unless noted otherwise, all specifications apply over the operating temperature range with filter
soldered to the specified demonstration board with impedance matching to 50
and measured
with 50
network analyzer.
Unless noted otherwise, all frequency specifications are referenced to the nominal center fre-
quency, fc.
Rejection is measured as attenuation below the minimum IL point in the passband. Rejection
in final user application is dependent on PCB layout and external impedance matching design.
See Application Note No. 42 for details.
The turnover temperature, T
O
, is the temperature of maximum (or turnover) frequency, f
o
. The
nominal frequency at any case temperature, T
c
, may be calculated from: f=f
o
[1-FTC(T
o
-T
c
)

].
The design, manufacturing process, and specifications of this filter are subject to change.
Either Port 1 or Port 2 may be used for either input or output in the design. However, imped-
ances and impedance matching may vary between Port 1 and Port 2, so that the filter must
always be installed in one direction per the circuit design.
US and international patents may apply.
Electrostatic Sensitive Device. Observe precautions for handling.
